EL4431: Video Instrumentation Amplifiers

The EL4430 and EL4431 are video instrumentation amplifiers which are ideal for line receivers, differential-tosingle- ended converters, transducer interfacing, and any situation where a differential signal must be extracted from a background of common-mode noise or DC offset.

These devices have two differential signal inputs and two differential feedback terminals. The FB terminal connects to the amplifier output, or a divided version of it to increase circuit gain, and the REF terminal is connected to the output ground or offset reference.

The EL4430 is compensated to be stable at a gain of 1 or more, and the EL4431 for a gain of 2 or more. The amplifiers have an operational temperature of -40°C to +85°C and are packaged in plastic 8-pin DIP and SO-8. The EL4430 and EL4431 are fabricated with Elantec's proprietary complementary bipolar process which gives excellent signal symmetry and is free from latchup.
